配置单段动态VPWS示例－使用LSP隧道

操作步骤

1. 配置CE上接入PE的接口的IP地址

   # 配置CE1。

   <HUAWEI> system-view

   [~HUAWEI] sysname CE1

   [*HUAWEI] commit

   [~CE1] interface gigabitethernet 1/0/0

   [*CE1-GigabitEthernet1/0/0] undo shutdown

   [*CE1-GigabitEthernet1/0/0] quit

   [*CE1] interface gigabitethernet 1/0/0.1

   [*CE1-GigabitEthernet1/0/0.1] vlan-type dot1q 1

   [*CE1-GigabitEthernet1/0/0.1] ip address 10.10.1.1 24

   [*CE1-GigabitEthernet1/0/0.1] undo shutdown

   [*CE1-GigabitEthernet1/0/0.1] commit

   [~CE1-GigabitEthernet1/0/0.1] quit

   # 配置CE2。

   <HUAWEI> system-view

   [~HUAWEI] sysname CE2

   [*HUAWEI] commit

   [~CE2] interface gigabitethernet 1/0/0

   [*CE2-GigabitEthernet1/0/0] undo shutdown

   [*CE2-GigabitEthernet1/0/0] quit

   [*CE2] interface gigabitethernet 1/0/0.1

   [*CE2-GigabitEthernet1/0/0.1] vlan-type dot1q 2

   [*CE2-GigabitEthernet1/0/0.1] ip address 10.10.1.2 24

   [*CE2-GigabitEthernet1/0/0.1] undo shutdown

   [*CE2-GigabitEthernet1/0/0.1] commit

   [~CE2-GigabitEthernet1/0/0.1] quit

2. 配置MPLS骨干网的IGP

   在MPLS骨干网上配置IGP，本示例中使用OSPF。有关OSPF的配置，请参见《NetEngine 8000 配置指南 IP路由》中的“OSPF配置”。

   具体配置过程略。

3. 使能MPLS，建立隧道和LDP远端会话

   在MPLS骨干网上使能MPLS，并在PE之间建立LSP隧道和LDP remote session。

   具体配置过程略。有关MPLS的配置，请参见《NetEngine 8000 配置指南 MPLS》。

   完成此步配置后，执行命令display mpls ldp session可以看到PE之间、PE与P之间建立了LDP Session，且状态为Operational。

   以PE1的显示为例。

   <PE1> display mpls ldp session

    LDP Session(s) in Public Network
    Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDD:HH:MM)
    An asterisk (*) before a session means the session is being deleted.
   --------------------------------------------------------------------------
    PeerID             Status      LAM  SsnRole  SsnAge       KASent/Rcv
   --------------------------------------------------------------------------
    192.168.3.3:0        Operational DU   Passive  000:00:00    4/5
    192.168.4.4:0        Operational DU   Passive  000:00:02    10/10
   --------------------------------------------------------------------------
   TOTAL: 2 Session(s) Found.

4. 创建VPWS连接

   在PE1、PE2上使能MPLS L2VPN，在两个PE上创建VPWS连接。

   # 配置PE1。

   [~PE1] mpls l2vpn

   [*PE1-l2vpn] quit

   [*PE1] interface gigabitethernet 1/0/0

   [*PE1-GigabitEthernet1/0/0] undo shutdown

   [*PE1-GigabitEthernet1/0/0] quit

   [*PE1] interface gigabitethernet 1/0/0.1

   [*PE1-GigabitEthernet1/0/0.1] vlan-type dot1q 1

   [*PE1-GigabitEthernet1/0/0.1] mpls l2vc 192.168.3.3 100

   [*PE1-GigabitEthernet1/0/0.1] undo shutdown

   [*PE1-GigabitEthernet1/0/0.1] commit

   [~PE1-GigabitEthernet1/0/0.1] quit

   # 配置PE2。

   [~PE2] mpls l2vpn

   [*PE2-l2vpn] quit

   [*PE2] interface gigabitethernet 1/0/0

   [*PE2-GigabitEthernet1/0/0] undo shutdown

   [*PE2-GigabitEthernet1/0/0] quit

   [*PE2] interface gigabitethernet1/0/0.1

   [*PE2-GigabitEthernet1/0/0.1] vlan-type dot1q 2

   [*PE2-GigabitEthernet1/0/0.1] mpls l2vc 192.168.2.2 100

   [*PE2-GigabitEthernet1/0/0.1] undo shutdown

   [*PE2-GigabitEthernet1/0/0.1] commit

   [~PE2-GigabitEthernet1/0/0.1] quit

5. 验证配置结果

   在PE上查看VPWS连接信息，可以看到建立了一条VC，状态为UP。

   以PE1的显示为例：

   <PE1> display mpls l2vc interface gigabitethernet 1/0/0.1

   *client interface       : GigabitEthernet1/0/0.1 is up

   CE1和CE2应能相互Ping通。
